Be it known that I, GUSTAF E. ER1CKSON,L citizen of the United States, residing at Iron Mountain, in the county of Dickinson and State of Michigan, have invented certain new and useful Improvements in, Puzzles, of which the following is a specification, reference being had to the accompanying drawl his invention relates to an improved puzzle and more particularlyv to puzzles of that character commonly known as block puzzles.

The object of the present invent1on.resides in the provision of an exceedingly perplexing and intricate puzzle of the above character which will provide a severe test for the ingenuity of one attempting to solve the same, and consists of a plurality of blocks or bars formed with co-engaglng mortises and lugs, and a sectional key block adapted when properly fitted with the assembled blocks or bars to lock the whole together and form a symmetrical geometrical figure.

A further object of the invention is to provide a puzzle which may be manufactured at a slight cost and one which will afiord considerable amusement and pleasure, while at the same time it is sufliciently difiicult of solution to require considerable manipulation of the various elements before success is obtained. 7

With these and other objects in view, the invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully, described and claimed, and illustrated in the accompanying drawings, in whicl1- Figure 1 is a perspective view of a puzzle constructed in accordance with the present invention, showing the parts assembled.

Figs. 2, 3 and 4 are similar views illustrating successive steps in the solution of the puzzle. Fig. 5 is a detail perspective view of the sectional key block. Fig. 6 isa sec tion taken on the line 6-6 of Fig. 1. Fig. 7 is asection taken on the line 77 of Fig. 1. Figs. 8 and 9 are detail perspective views of certain of the puzzle blocks, and Figs. 10 and 11 illustrate detail perspectiveviews of the pairs of blocks 5, 5 and 8 8 respectively.

Referring more particularly to the draw ing 5, 5* indicate the two base pieces upon which the puzzle structure is adapted to be built. These base pieces are provided in their outer edges with the mortises or recesses 6, and a -lug 7 is also formed on each base piece and extends into one end of the recess 6. In assembling. the blocks, the base pieces are adapted to be arranged with their plane surfaces together, as clearly shown in Fig. 2. The first step in the assemblage of the puzzle blocks is to arrange the pieces 8, 8" in the mortises 6 of the base blocks 5, '5. The opposed faces of the pieces 8, 8 are longitudinally recessed or cut-away, as shown at 9, the said cut-away portions extending substantialla one half of the thickness of the block and terminating a short distance from each end thereof. One edge of the pieces 8, 8 is notched, as indicated at 10. These notches are adapted to receive portions of suitable key iece'swhereby the several blocks are held in their assembled positions, as will be more fully hereinafter set forth. After these four pieces have been similar blocks 11 are next placed in position. These blocks are cut-away longitudinally, as shown at 12, in a similar manner to the blocks'8, 8 and in these cut-away portions of said blocks 11, the base blocks 5, 5 are received. The blocks 11 are, however, unlike the blocks 8, 8 also cut out or mortised longitudinally between their ends in their opposed edges, as shown at 1,3. In the ends of these cut-away edges the blocks 8, 8 are disposed, the end portions of the blocks 11 extending upon the outer faces of the blocks 8, 8. The next step in the formation of the figure is illustrated in Fig. 4 and consists in the placing of the block 14 in position between the opposed inner cut-away faces of the blocks 8, 8 and beneath the base pieces 5, 5 and the blocks 11, the-said block 14 being also longitudinally cut-away upon one face, as indicated at 15, to receive the blocks 11, the ends of the cut-away faces of the blocks 14 abutting closelyagainst one side of the base pieces 5, 5. The last step in assembling the puzzle is the insertion of the block tioned block 14, between the opposed inner cut-away faces of the blocks 8, Stat their upper ends, Before the insertion of ,the block 14 in posit-ion, the block 16 is seated block 14' and moves inwardlyupon thelf moved to position. This movement of the of the base blocks 5, 5= as theblock, 144,45.

arranged, as shown in the drawing, the two 14, similar in all respects to the aforemenin-one end of the cut-away facejlo of the block 14' positions the ends of the 16 I engaging with each of the aforementioned blocks to closely unite the same. i

4. A block puzzle comprising base blocks adapted to be arranged upon each other, other blocks adapted to be disposed upon opposite faces of the base blocks and over their engaged edges,said latter blocks and the base blocks being provided with recesses, a plurality of blocks to be received in said recesses and extending at rightangles to the aforesaid blocks, said last named blocks being also recessed, additional blocks extending through said recesses and the re- ,cesses of the base blocksand engaging over the second named blocks, and a key block 15 GUST.
